R3112N121A-TR-F - Brand New RICOH IC Chips
-
Description
The R3112x Series is a CMOS-based voltage detector IC used for system reset. It is known for its high detector threshold accuracy and ultra-low supply current. The IC consists of a voltage reference unit, comparator, resistor net for detector threshold setting, output driver, hysteresis circuit, and output delay circuit. The detector threshold is fixed internally with high accuracy and does not require any adjustment. Two output types, Nch open drain, and CMOS are available.
